Trombone Champ is probably best played in a party setting, as to start with especially to people unaware of what they're about to see it can be funny.

However, that kinda dies down very, and I mean very, fast.
It's pretty much standard rhythm type game, though I found it way more lenient and you don't have to have pinpoint accuracy when hitting notes - so long as you end on the correct spot you're all good.

I've finished all tracks so I'm counting that as a complete and 'Maybe probably will never return to'
